I am not properly understanding this question. please help!
Most of the process on PV diagram have this kind of curvature
But in the question above, its bit weird.
Pressure, temperature and volume all increasing.
So It looks like combustion process than expansion.
I am unable to figure out answer for it. They all seems correct.
There is definitely net work (-ve may be but there is net work)
Not sure about Net heat output.
As expanding density might decrease but pressure is increasing so it might increase.
And enthalpy is more likely to increase as all the quantities are increasing.
Please clarify the above thoughts and explain the answer.
I searched a lot all over the internet. Did not found any process look similar to this!
